This may have been the noisiest night of the year so far!   It seems that almost every station in North America was affected by this system in some way.  Given the amount of lightning that was present ( almost 10000 strikes in 12 hours! ) I hope everyone in the region weathered the storm safely and without incident.

12-hour North American lightning summary

 

Propagation was weird and active.  There were the usual big trans-Atlantic and trans-Pacific openings but the numbers of North American stations experiencing these openings was down, particularly on the trans-Atlantic paths.  Its almost as if the spotlight narrowed significantly for just a few stations.  Were the reported stations representative of the peaks or were there better location that might yielded even more long haul reports?  Only one European station was reported in North America which was almost certainly due to high noise but the band was very open and very long overland reports were noted between Europe and Asia which has been rare this season so far.

Geomagnetic conditions were elevated but quiet until this morning when storm levels were achieved as a new coronal hole became geoeffective.  The Bz had pushed strongly to the South with solar wind velocities exceeding 600 km/s for several reporting periods and diminishing to an average of 550 km/s  for persistent periods this morning before increasing again.  DST values took significant dives although the Kyoto DST appears more impacted than the Australian DST value so far.  Laurence, KL7L / WE2XPQ, reported very strong visual aurora  at 1010z.  It’s been a while since we have observed such a hot coronal hole and solar wind stream.

 

 

 

This session ushered the return of the very long and unlikely openings from Europe to Asiatic Russia.  PA0A and DJ0ABR made the very long haul trip to UA0SNV on a path that has been absent for virtually all of this season thus far.  While long haul openings occur almost every night, this nearly 5600 km path is completely over land which is remarkable.  Report details for these stations can be viewed here.

Trans-Atlantic reports were very active but the distribution of North American stations was much smaller than the previous session suggesting that the spotlight focused into very narrow, localized beams for very short periods of time.  Noise limited European stations reported in North America to only one.  Report details can be viewed here.

Paul, N1BUG, reported that he decoded ten WSPR stations in spite of very high QRN including WH2XGP on the transcontinental path from Maine.  Paul has been assigned WI2XTC by OET and now his Part-5 grant application has been shipped off to NTIA for scrutiny and approval.

Rick, W7RNB / WI2XJQ, reported a poor session where his decodes retreated due to storm QRN in the Midwest.  Rick provided reports for seven WSPR stations and was reported by 24 unique stations.  Rick’s unique report details can be viewed here.

Ken, K5DNL / WG2XXM, was one of the stations to have a big night, decoding four WSPR stations and being decoded by 74 unique stations including OR7T, PA0O, F59706, G8HUH, G3XKR, F1AFJ, G8LCO, G4KPX, PA0RDT, WH2XCR, ZF1EJ, and 10 VE stations.

Trans-Atlantic openings to Japan from North America where joined by some improvements on the path to Australia.  Report details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, reported some good news:  “Internet back after hours of cajoling. QRN down, but still pretty bad. TP propagation fair to good. 630m/160m results with VE6XH are 160m 5 spots, best -15, 630m 12 spots, best -21”  Roger received reports from CF7MM, VE6XH, and W7IUV.  He provided reports for WH2XGP and WH2XXP.

Ward, K7PO / WH2XXP, received reports from 59 WSPR stations including VK4YB, JA1NQI, JA3TVF, JH1INM, ZL2AFP.

Larry, W7IUV / WH2XGP, received reports from 46 unique stations including VK4YB, JA1NQI, ZL2ZFP.  Larry provided reports for eight WSPR stations.  As W7IUV, Larry provided reports for seven WSPR stations including VK4YB.  Larry added that, “Very poor RX last nite on all frequencies. Bad QRN here, but XGP was heard around the globe indicating fair prop”

It was tough going here in Texas during this session but listening conditions seemed to improve overnight.  It was obvious even before sunset that any operating activities extending beyond WSPR were likely not going to happen due to the noise.  WG2XKA located in Vermont and I had discussed a JT9 QSO earlier in the day but evening WSPR reports suggested that I would not hear him and the reciprocal was probably true as well.  Interestingly enough, even with all of the noise, my listening total were greater than they have been in a week, exceeding 1000 stations for the session.  Those reports can be viewed here.  My WSPR transmission reports were equally robust and can be viewed here but no trans-Atlantic reports during this session.  I just wasn’t in the spotlight  and it didn’t seem to extend this far South.  Hopefully noise conditions will be better tonight and I can return to real operating.  Stay tuned!

Laurence, KL7L / WE2XPQ,  reported that he would be QRT for a few nights.

Merv, K9FD/KH6 / WH2XCR, took advantage of nice openings to Japan and Oceania during this session, including reports from JH3XCU, JA1NQI, VK2XGJ, ZL2AFP and two-way reports with VK4YB.  Merv also shared two-way reports with ZF1EJ and he provided reports for VK3HP.  Merv noted yesterday that a strong storm system would be passing over Molokai over the coming days but it did not seem to impact his hearing too much, as he decoded WG2XPJ in Vermont.  There is a significant hole in activity in the East and Midwest due to strong storms in North America.  Coverage in the central US and western regions of North America was typical and quite good.  Merv’s DX report details can be viewed here.
